FREDRIOK G. ROGERS, OF BUFFALO, NEW YORK.

CLEANER FOR STEAM-BOILERS.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed March 13.1906. Serial No. 305,784.

To all whom t may commit/zi.-

Be it known that l, Frommen G. Roo- ERS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented 'a certain new and useful Improved Cleaner for Steam-Boilers, of which the following is a specification.

This invention relates to an improved cleaner for steam boilers and particularly to a device for purifying the water.

The object of the invention principally is to prevent the formation of scale and consequently maintain a uniform boiler heating capacity, economize in fuel consumption', and obviate any danger from uneven overheating of the boiler surface.

The invention also relates to cer tain details of construction, all of which will be fully and clearly hereinafter described and' claimed reference being .had to the :uzcompanying drawings, in which,-

Figure 1, is a vertical longitudinal section through a furnace and boiler equipped with my improved purifying device. Fig. 2, represents in one half a front elevation of, and in the other half, a transverse vertical section through a furnace and boiler equipped with the improved purifying device on line a-a, Fig. 1. Fig. 3, is an enlarged vertical transverse section through the boiler proper, or main water chamber of a water tube boiler, provided with the improved purifying device, on line a-a, Fig. 1. Fig. 4, is an enlarged fragmentary bottom view of the blow out pipe for renmving the impurities from the urifying device. Fig. 5, is a detached enarged top .lan view of the preferreiil form of purifying f evice. Fig. 6. is a vertical longitudinal section on line b-), Fig. 5. Fig. 7, is an enlarged vertical transverse section on line c-c, Fig. 6, looking in the direction of the arrow V. Fig. S, is an enlarged detached bottom view of one of the lower partitions. Fig. 9, is an enlarged vertical transverse section on line (il-d, Fig. 6, looking in the direc-- tion of the arrow X. Fig. .10, is an enlarged detached top view of one of the upper partitions. Fig. 11 ,is an enlarged vertical trans verse section on line ew-c, Fig. 6, looking in the direction of the arrow Z.

In referring to the drawings for the details of construction of the preferred adaptation of my invention therein shown, like numerals designate like parts.

lhile the form of the improved purifier shown is particularly adapted to be used in conjunction with a water tube boiler of the type illustrated, it may, with some slight changes, be employed in any of the well known styles of boilers.

'.lhe boiler is mounted in a furnace or heater 1, of well known type, and comprises a main cylindrical water chamber or tank 2, located in the upper portion of the furnace and extending horizontally and longitudinally through the furnace from the front to the back thereof, a series of diagonally extending longitudinal tubes 2%, arranged below the main water chamber 2, and connected at their ends by the front and rear boxes 4 and 5, which in turn are connected to the main water chamber 2, by pipes 6 and 7, so that a continual circulation of water .is maintained through the boiler parts when the furnace or boiler is running.

A mud drum 8, is located in the lower rear corner of the furnace which is connected to the rear box 5, by a pipe 9, see Fig. 1.

The preferred type of purifying device comprises a plurality of long troughs arranged horizontally side by side and parallel to each other. In the drawings two troughs are shown in horizontal side by side position and located in the main chamber or tank 2. 'lo support the troughs in position, opposed brackets 10 and 11, are fastened by tap bolts 12, or other suitable means to the opposite sides of the interior of the tank, see Fig. 3, and are secured to the troughs by bolts 13, or similar fastenings.

The brackets 1 0 and 11, it shoulde be noted are of a peculiar' curved or angular form, having enlarged upper ends provided with flat sides which are bolted to the sides of the troughs and curved and flanged and tapering portions which conform to the curved interior surface of the tank and depend below the enlarged upper ends being fastened at suitable intervals to the tank by bolts.

By referring to Fig. 3, it will be noted that the troughs the connecting pipes and the brackets form a horizontal connection between opposite sides of the tank, thereby not only securing the troughs very rigidly in place but also decidei-lly strengthening and stiflening the tank itself. Another advan tage is that the top and bottom of the tank is left lree from obstruction for the brackets are located at and attached to the sides. This also renders the brackets very accessible by detachment or attachment.

The troughs are connected to each other at IOO IlO

or near one end by a transverse pipe 14, which is connected to a water inlet pipe 15, and at or near the opposite end by a transverse pipe 16, from which an outlet pipe 17, extends vertically downward to near the bottom ofthe tank 2see Fig. 1.

The troughs are formed from sheet metal or other suitable material. The trough, as preferably constructed, consists of a curved or rounded bottom plate 18, side plates 19, and 20, which are lapped upon and fastened to the bottom plate by bolts 21, and end plates 22 and 23, each of which is secured in proper position at the respective ends of the trough by bolts 24, which pass through the end plates and side and bottom plates and the connectingand supporting angle irons 25.

A series of upper and lower transverse vertical partitions 26, and 27, are located at suitable intervals in the trough and in alternate arrangement so that the water will follow the sinuous path indicated by the arrows in Fig. 1, in passing through the trough. The purpose of these partitions is to interrupt and impede the straight flow of the water i and thus secure a better precipitation of the impurities in the water to the bottom of the trough.

A blow out pipe 28, extends longitudinally in the trough from near one end to and through the opposite end from whence it eX- tends through the end of the tank 2, to any suitable locality. The blow out pipe 28, is located near the bottom of the trough being supported in position by the lower partitions 27, and the end plate 23, of the trough through openings in which it extends. The end of the blow out pipe 28, within the trough is closed bya cap 29, see Figs. 1 and 4. Diagonal slots or openings 30, are cut in the under surface of the blow out pipe at suitable intervals, see Figs. 4, 7 and 11, through 'which the settled impurities are removed when the blow out cock 31, shown in Fig. 1, is opened.

It will be noted by referring to Figs. 7, 9 and 11, that the blow out pipe 28, is centrally arranged in the space formed by the curve of the bottom plate of the trough, so that the impurities naturally slide gradually or move into position beneath the blow out pipe and are thus collected in the best place for quick removal.

By employing two or more troughs the troughs may be made smaller in diameter so that the water will be divided into streams of comparatively small volume so that better purification is more thoroughly and quickly secured. Besides either of the troughs can be quickly cleaned by opening the cock 31, of its blow out pipe 28, and thereby permitting the interior boiler pressure to force the iinpurities and sediment collected in the bottom of the trough out through the blow out pipe.

This improved purifying device is adapted to be used with nearly all of the well known styles of boilers and is intended to remove a large percentage of the impurities from the water before it is introduced into the boiler.

The operation of the invention will be readily understood from the foregoing description and drawings. In this improvement the water flows into all the troughs through the transverse trough connecting pipe at one end and flows out from all the troughs through the transverse trough connecting pipe at the opposite end, thereby dividing the water into two or more smaller streams of small volume each of which io'ws through a separate independent trough, and then reuniting the streams after their passage through the troughs. This not only increases the rapidity of the flow of water but also renders the cleansing action more thorough and complete.
